Description

The invention relates to a paint composition for painting upper surfaces.

The painting of eggs, for example by means of so-called Gloss colors, is generally done by the fact that the color mass of the desired color applied to the hot egg will. The color mass is in the form of a relatively thick Chopsticks in a plastic or aluminum foil kelt, which is torn open at one end before application. The color mass has a gelatinous appearance at room temperature Consistency and liquefies at elevated temperature. This known painting technique has the disadvantage that on the one hand the Manageability of the flexible, wrapped in a foil, thick sticks, especially when partially used up ter paint mass, requires some skill, as the in the film wrapped paint at the same time bil the handle det. On the other hand, it is necessary that the surface on which the paint is to be applied is sufficient has high temperature. In the event of an interruption in the Painting work must therefore z. B. reheat the egg, which leads to problems, especially with partially painted eggs can lead. Furthermore, such paint sticks have a dic ke line width, so that practically only a flat one coloring is possible, while painting with finer contour and painting of cold surfaces is excluded is.

EP 0 164 074 A2 relates to a thermal transfer recording medium material, which is a donor sheet with a heat fusible Ink layer on a support and an image-receiving sheet holds, with either the donor sheet or the image receiving the lower leaf or both leaves are marked that the heat fusible ink layer on the donor sheet is in the essentially a colored dye or pigment Comprises binder and a wax and the image-receiving Sheets a coating with a heat-fusible substance having. Gelatin can be used as a binding agent Find.

The invention is based on the object of providing a color composition with which the painting of surfaces, such as eggs, Foils or the like. Is simplified.

The object is achieved according to the invention in that the Color mass by a composition of gelatin, at least a solvent and humectant, at least one preservative vierungsmittel, at least one buffering agent to stabilize lization of the gelatin, at least one color pigment and egg with a residual proportion of softened water. This color mass can be a paste or at room temperature have gelatinous consistency and at increased temp to liquefy the temperature.

In a particularly preferred embodiment, this is provided hen that for all components of the composition substances ver are used, which have food quality or as Food additives are permitted. This offers the guarantee that the paint in connection with painting implements can be used by smaller children det, where it cannot be ruled out that The paint gets into the mouth during handling. With a such color mass can be the most varied of surfaces to be painted. This is a special area of application Painting eggs and painting transparent foils for the production of so-called window pictures. Leave as foils use commercially available foils, e.g. made of PE, PET, PP or PVC. The attachment of the foils to the window or on other substrates either with the appropriate Finishing of the film by self-adhesion or by a Be one side of the film is layered with adhesive. It is also possible, a normal foil with a special adhesive to provide fabric subsequently. Because the paint itself is on due to their composition a certain adhesive effect it is also possible after painting the foil with the painted side directly on the glass surface of the To bring up windows. If you put a "colorless" color of the composition according to the invention, d. H. let the in the composition given away dye, results a "glue" to apply the film to the windows disc. This has the advantage that any foils ver can be turned. The slides should have a good manageability have sufficient stability, for easy painting on the foil without creasing enable. Because the color mass was in its composition is soluble, there is also the possibility of the color un to be applied indirectly to the window pane.

In an embodiment of the invention, a basic composition is provided for the color mass, which is formed from a mixture of

gelatin 5-40 preferably 10-30 Solvent / humectant 3-50 preferably 10-20 Preservatives 0.01-2.0 preferably 0.05-1.0 Buffering agents 0.005-2.0 preferably 0.1-1.0 Dyes 0.01-5.0, preferably 0.05-2.0 Softened water ad 100

(all proportions in% by weight).

The composition given below is particularly advantageous:

gelatin 15-25 Solvent / humectant 10-20 Preservatives 0.1-0.8 Buffering agents 0.15-0.5 Dyes 0.1-1.0 Softened water ad 100

(all proportions in% by weight).

The use of types of gelatin is particularly advantageous in food quality, as this has a very low intrinsic color have exercise, so that here in particular when using formation of basic dyes translucent shades of high brilliance can be achieved.

In an embodiment of the invention it is provided that as a release and / or humectants can be used: diethylene glycol and / or ethanol and / or methoxypropanol and / or lactic acid reethyl ester (trade name Lactonal) and / or 1,2-propylene glycol and / or methoxypropanol and / or dimethyl sulfoxide and / or glycerol diacetate and / or 1,4-butylene glycol and / or 1,2,4-butanetriol and / or triethylene glycol monomers ethyl ether and / or triethylene glycol dimethyl ether and / or Diethylene glycol monoethyl ether and / or acetic acid-2-methoxy ethyl ester and / or ethylene glycol and / or N, N-dimethyl form mamid and / or polyglycols.

In an embodiment of the invention, it is also possible as Moisturizers / solvents mono- and / or oligo-saccharides add, in particular sucrose and / or glucose and / or Fructose and / or sorbitol. These humectants / solvents can on their own or in a mixture with other solvents can be used.

Regarding the preservative to be used basically no restrictions. It can all ver addable preservatives are used. Is preferred however, that as a preservative at least one as Le Food-preservative approved agent used will. In particular a mixture of a PHB ester mixture and benzoic acid.

In an embodiment of the invention, a buffer means is a Acid and / or an acid mixture, in particular one or several polybasic organic acids are provided. The puff agent serves to stabilize the gelatin and is with a pK- Value inserted.

Tartaric acid can be used as the polybasic organic acid, Malic acid, ascorbic acid or similar acids. Especially be preferred, however, is suitable because of its cheap pKs who tes and the cheap price citric acid. In addition to the before The polybasic organic acids mentioned above is also the Use of monobasic organic acids, for example Amino acid possible.

In principle, all water-soluble dyes are suitable as dyes Dyes. Use is particularly advantageous here of so-called basic dyes, which are already in extremely produce brilliant colors in small quantities. But also the Use of water-dispersible pigments, in particular Food coloring pigments, is possible. Here are however higher concentrations necessary. When using color Fabric pigments, however, tend to produce opaque color effects. The use of microfine pigments still gives the advantage translucent color effects, being an additional benefit gives a high lightfastness, what for use as Window pictures matter. The installation usual effect pigments, such as surface treated mica or polyester glitter pigments is also possible. As be is preferred with regard to the handling by children Use of so-called food colors. Below drop any coloring after the food additive Admission Ordinance are approved. The use of the he inventive recipes also has the advantage that the paint application even after a longer period of time by on soak can be removed from the painting surface with water. In the Using foils, this has the advantage that the foil can be used multiple times. Another benefit lies in that the paint when the hands are dirty or on whose substrates can be removed better than simple ones aqueous solutions of food coloring without gelatin add.

The color mass can be used in a painting device, which has a has filled or fillable container with a ka is provided with a needle-like paint tip. The color mass can thereby preferably paste or gelatinous at room temperature term consistency and at elevated temperature liquefy. To use the painting device, this is included with with the paint tip pointing upwards, for example in a hot tub serbad heated to approx. 40 to 60 ° C, so that the color liquefied mass. After that, the color mass can then with the help the tip of the paint without further ado on the cold upper surface to be painted surface can be applied in fine contours. After the opening The painting device can put the desired color back into the A water bath can be placed in which the color mass is restored warms and is kept fluid. In particular, there is a The advantage is that the surface to be painted, for example se of an egg, no longer needs to be heated, so that with the like gloss colors an egg also "painted" with several colors and can not only be colored in one color.

It is possible that the container is at least partially a deformable, preferably at least partially through made of translucent plastic. This has the advantage that for the paint mass by squeezing the container through the paint tip pushed out and applied to the surface gen and on the other hand, the color of the paint mass is easily recognized can be. When manufacturing the container from plastic it is also useful that the paint tip on the Behäl ter is molded.

Furthermore, it is advantageous if the container has a substantially chen elongated, cylinder-like shape with one against the mark having a pointed conical end to be bought. This allows the Manageability of the painting device can be further improved. Fer It is possible that by cutting off the tip of the paintbrush different points of the tapered section each because an outlet opening with a different cross-section can be formed so that a painting with different chen line widths is possible.

It can be useful that the container with the paint tip consists of a shell-shaped plastic film, their open side after being filled with a paint compound is sealed with a heat seal film. This training has the advantage that the painting device is easily made and the Be container can be filled in a simple manner with the paint can, for example with an automatic filling machine. Also for this the paint composition according to the invention is advantageous because the Possibility of liquefaction due to the influence of temperature simple dosed filling of the painting device becomes possible. Ins special it is possible that to open the paint tip this only has to be cut open, for example with a pair of scissors.

It can be useful for the production of packaging units be moderate that more from a sheet of film by deep drawing bowl-shaped containers connected to one another on the right edge, each with a paint tip, which are formed after filling with one or more different colored masses with a heat seal covering the entire sheet of film foil is closed. It can be provided that for example four different colors next to each other a sheet of film are made. The contiguous times devices can be packed in an outer packaging and then to be offered for sale. It is for use only required that the individual painting devices, for example with a pair of scissors to be separated from each other.

To improve the manageability, it can be useful that the heat-sealing film with a metallic reinforcement foil is provided. This can ensure that by squeezing the container to apply the Color mass does not destroy the heat-sealing film and an unge intentional leakage of the paint is avoided.

In a further embodiment it is possible that the Be container made entirely of plastic and with a tightly closable refill opening is provided. Included it may be appropriate that the closure element of the after filling opening at the same time the cannula-like paint tip shows. This makes it possible for the paint to be used as a stabför Miges refill element can be used in the painting device. In particular, it is possible that by the essay from under different painting tips with different cross-sections openings a painting of the surfaces with different Line widths can be done.

Such a painting device is explained in more detail below with reference to the drawing explained. Show it:

Fig. 1 is a view of a painting device,

FIG. 2 shows a section along the line II-II according to FIG. 1,

Fig. 3 is a section along the line III-III of FIG. 2,

Fig. 4 in section several coherent time devices according to Fig. 1 and

Fig. 5 is a view of a Malgerätes according to another embodiment.

The painting device 1 shown in the drawing has an elongated container 2 with a substantially semicircular cross-section. The container 1 is provided with a cannula-like paint tip 4 at its one end 3. In an individual, the arrangement is made so that the container 1 and the paint tip 4 are in communication with each other via a tapered area 5 and are formed together by a deeply drawn plastic film. The flat side 6 , ie the initially open side of the approximately bowl-shaped Behäl age 1 and the paint tip 4 are sealed with a heat-sealing film 7. For this purpose, the deep-drawn film has a umlau fenden edge 8 , with which the heat-sealing film 7 is sealingly connected.

At least inside the container 1 , but also partially in the paint tip 4, there is the paint mass 9 which can be liquefied by heating and which forms an essentially gelatinous mass at room temperature. It can be advantageous if at least the plastic film forming the container 1 is at least partially made of translucent material, so that the color of the corresponding paint 9 can be easily recognized.

To use the painting device, the paint tip 4 is, for example, cut open with scissors along the line 10 shown in dash-dotted lines in the drawing and the edges of the edge 8 are bent up in this area, so that an opening is created through which the paint can escape from the container . In the exemplary embodiment shown in the drawing, the cannula-like paint tip is designed as an approximately cylindrical tube. But it can also be provided that the paint tip itself is also tapered so that depending on the position of the interface 10 to the closed end 11 of the paint tip 4 openings with different cross-sections arise. This means that a painting device can be created for different line widths.

In Fig. 4, a packaging unit formed from several coherent painting devices according to FIG. 1 is in section Darge provides. In this case, a plurality of containers 12 arranged parallel to one another are formed from a sheet of film 15 by deep drawing hen. On their flat side 16 , the containers 12 are closed with a heat-sealing film 17 after they have been filled with one or more differently colored masses of paint. Before use, the individual painting devices, for example ent long the dash-dotted lines 20 , separated from one another by means of scissors. The dimensions between the individual containers 12 are so dimensioned that after the Durchtren voltage a sufficiently wide web 18 is still present, with which the heat-sealing film 17 is tightly connected.

In Fig. 5, a painting device 21 is shown, which has a container 22 which has at its one end a by a Ver closing element 24 tightly closable refill opening 23 has. The container 22 is made entirely of preferably translucent plastic. At its end facing away from the container 22, the closure element 24 is designed as a cannula-like paint tip 25 .

The closure element 24 is sealingly connected to the container 22, for example, by screwing or by interlocking before cracks and recesses. It may be useful that the container 22 is made of elastically deformable Mate rial, so that the paint can be pushed out by squeezing the container through the paint tip 25 on the upper surface to be painted.

Such a design of the painting device with a ver closable refill opening has the advantage that the paint can be refilled, for example from a reservoir in liquid form, but preferably by entering a gelatinous paint stick, which is liquefied under the influence of heat. Before using such a painting device for the first time, it can be provided that the container 22 is already filled with paint and the filling opening 23 is closed with a heat-sealing film 27 . For the use of Malgerätes it is only erforder Lich, that the heat sealing film 27 is peeled off prior to fitting of the closure element 24 formed as a painting tip 25th This arrangement has the advantage that the paint is largely avoided before it is used for the first time.

It has been found that for the purpose and with regard to the mix of colors in multi-layered Apply five dyes are sufficient. When using the Dye Quinoline Yellow 70% (E 104) with a proportion of 0.30% by weight results in a yellow color. If you put the sen dye in a proportion of 0.30% by weight together with lisamine green (E 142) with a proportion of 0.2 Ge weight%, the result is a shade of green. Through the use application of patent blue V gran. (E 131) with a share of 0.10 Weight color mass results in the color shade blue. Through the Use of the dye Azorubin S (E 122) with one portion from 0.20% by weight the color red is achieved. By ent Let a speaking mixture of different basic shades other shades can be achieved at night.

A pre-packed set can now contain one or more foils as painting surfaces as well as several painting devices with different colored masses are offered filled. For the slides Commercially available transparent foils are suitable, for example se made of PE, PET, PP or PVC. These slides can be either with an added adhesive, for example from the fiction according to the color mass without the addition of coloring agents after painting the window pane can be glued. But it is also possible Lich, without adhesive self-adhesive films or with a Adhesive layer and a clear protective film for the Use adhesive-coated foils. Such in transparent foils have become especially useful when they are in use through children the advantage that motifs of any Template that is also included in the set in the basic equipment can be, can be taken over. It is also possible, the film itself with the outlines of the motif to be painted to print. For foils with an adhesive layer and egg A protective layer for the adhesive is provided also the possibility to paint the motif on the protection layer to be printed so that when transferring with full constantly transparent foils on the finished picture the motif con doors no longer appear and thus the possibility be stands, the transitions between individual color tones also in To create border areas, as the black outlines do not appear on the slide.
